Granite and some of the similar stones are very unique materials in terms of their physical properties. Basically they are very thermally stable, which means they change very slowly with changes in temperature compared to other materials, particularly metals. They are very hard, giving them excellent resistance to wear. Because they are inert they do not require any type of coating (paint, plating, anodizing, etc.) for protection like most metals do. Due to the combination of these and other physical properties these stone materials can be manufactured to very small critical geometry tolerances. These stone materials are also excellent vibration absorbers.

We currently offer four materials for precision products: Impala (from South Africa), Zimbabwe (also from South Africa), our local Barre Gray Granite, and Salisbury Pink Granite (from North Carolina). Physical properties relevant to precision use vary significantly between these materials. Many physical properties need to be considered in determining the appropriate material for your application. This is best initiated with a phone conversation with Michael Caputo, perhaps followed at some point with a visit.
